This remix of the esp32-wroom case and the everything presence lite it's a versatile, pressure-fit wonder, requiring zero soldering or specialized tools; just snap that ESP32 Board together with the HLK-LD2450 sensor. Then, flash it with ESPHome using our custom configuration file, and voilà – you've created the foundation for your smart sensor!

With enough space left in the case, you can effortlessly expand its capabilities by incorporating a microphone, light sensor, temperature sensor, air quality sensor, or any other sensor that you want.

It mixes the standing base of the Everything Presence Lite, and the Body of the ESP32-Wroom Case to create a super flexible case, offering customizable positions for multiple use cases.

I adjusted the size of the pieces to ensure an easy assembly.

Printed with PLA, 40% infill.

If you are going to order it from PCBway, use something stronger like PTEG or Resin for the same price as PLA.
